UK practice is to adhere to the rule of thirds, but with an added emphasis on keeping depletion of your separate air systems " balanced ," so that the loss of a complete air system will still leave you with sufficient air to return safely.

Note that the rule of thirds makes no allowance for the increased air consumption that the stress caused by the loss of an air system will induce.

Note that the rule of thirds was devised as an approach to diving Florida's caves-they typically have high outflow currents, which help to reduce air consumption when exiting.

In a cave system with little ( or no ) outflow it is mandatory to reserve more air than is dictated by the rule of thirds.
